Former Vice President Joe Biden did not rule out launching a presidential campaign in 2020 during an interview on NBC’s "Today" show.

What did Biden say?

"I honest to God haven't made up my mind about that," Biden said of entering the race to challenge President Donald Trump. "I'm not closing the door. I've been around too long."

Biden, 74, said he is "a great respecter of fate” but is unsure “what the situation is going to be in a year-and-a-half.”

“I don't have any idea,” he said. “I'm in good health now. I'm in good shape, but I just don't know. Honest to God, that's the truth."

In the meantime, Biden said he wants to focus on his new book, "Promise Me Dad," about his son, Beau, and his battle with brain cancer. Beau Biden died at 46 in 2015. The former vice president said his son’s death impacted his decision not to seek the Democratic nomination for president in the 2016 election.

Asked if he thinks he could have defeated Trump in last year’s election, Biden replied, "Oh gosh, I don't know.”

"The polling data at the time said yes, but I wasn't in the race, you've got to be in the race. It's a tough game," he said.

Later, Biden told host Megyn Kelly that he still isn’t sure if he’s ready to seek the Democratic nomination for president because, following a loss, the second year of grief is sometimes worse than the first. He reiterated that he wants to focus on his book and getting a Democratic majority in the House in 2018.

“And then we’ll see,” Biden said.
